EXPERIENCE
VARIAN,
INC: Developed system selftest programs which have significantly reduced costs
and improved product quality of Varian Inova, Mercury
and InfinityPlus Nuclear Magnetic Resonance and
Magnetic Resonance Imaging instruments.
These selftest programs are
exhaustive (thousands of test steps) checks of gain, level, frequency, phase, modulation
and spectral characteristics, with shim and gradient current measurements.
Written in a variant of Pascal with C language pulse sequences, they run in a
UNIX environment. Detailed and summary test and troubleshooting records are
archived via a local network.
Developed a PC controlled test system
for frequency synthesizers, pulsed field gradient amplifiers and RF amplifiers
using IEEE 488 and Visual Basic. Synthesizer tests use downconversion to a period mode counter to make several
measurements per second with 0.1 Hz resolution. This test system significantly
reduced the rate of returns to OEM vendors.
WILTRON (now Anritsu): Developed impulse noise, return loss and
envelope delay measurements for T1 telephone test sets, using the TI TMS320 DSP
chip and band limited
interpolation.
Developed the time domain option for
the Wiltron 360 Vector Network Analyzer, using the chirp-z transform. Ported the chirp-z transform to the AT&T DSP32 chip.
UNITED AIRLINES:
Developed automatic test
equipment for altimetry, aircraft power, engine monitoring, fluid pressure
and flow, ground proximity warning and radio navigation, controlled via the
IEEE 488 interface.
HEWLETT-PACKARD: Designed the HP 9540 Automated Transceiver Test
System, using digital signal processing techniques to reduce instrument
count. Developed transceiver test program to EIA specs and
system selftest program in HP BASIC.
IIT RESEARCH INSTITUTE:
Conducted studies in the areas of EMC, EMP, ECM and radio receiver spurious
responses.
ZENITH RADIO CORPORATION:
Designed analog and RF circuitry used in production military search
radar applications of the Electron
Beam Parametric Amplifier.
